About the GPA Calculator
A grade point average is a credit-weighted mean, not a simple average of your letter grades. Each grade is converted to points on the 4.0 scale, multiplied by the credit hours of that course, and the total is divided by the total credits taken. A B in a four-credit lab therefore pulls harder than an A in a one-credit seminar, which is exactly why the arithmetic is worth doing properly.
Scales vary between institutions. Most American universities cap an A+ at 4.0 while some award 4.3, a few use plus and minus grades only for some ranges, and weighted high-school GPAs add a point for AP or IB courses. Set the A+ option to match your school, and remember that a cumulative GPA across several semesters is the same calculation applied to every course you have taken.
